FIELD OF INVENTION

[0002] The present invention relates to a cooling apparatus utilizing sportswear. Particularly, the invention is directed to a cooling apparatus comprising an insulated pouch positioned within the sportswear so that the pouch lies adjacent to the heart meridian.

BACKGROUND

[0003] The number of Americans who have at least one chronic illness was recently calculated to be 20 million more than experts had estimated. Researchers now calculate that over half a trillion dollars is spent in the United States for managing chronic illnesses such as heart disease, diabetes and high blood pressure.

[0004] Chronic illnesses, by definition, have no cure. Therefore, it is vital to adopt healthy lifestyle choices that help prevent chronic illness. Regular exercise can significantly reduce the risk of heart diseases such as cardiomyopathy or heart failure.

[0005] In particular, cardiomyopathy, a disease of the heart muscle, wherein the heart loses its ability to pump blood affects about 50,000 Americans. Regular physical activity is a key part of managing problems associated with this disease. Heart patients who increase their physical activity also boost their confidence, increase their fitness level, cut their risk of dying, report less depression, stress, and social isolation and improve their overall sense of well-being.

[0006] One of the most important components of an exercise program for heart patients whether they have cardiomyopathy or other common heart diseases is aerobic exercise. Aerobic exercise involves using large muscle groups rhythmically for prolonged periods, such as in walking, jogging, biking, rowing, swimming, etc.

[0007] During aerobic exercise, the body's temperature increases in direct proportion to the exercise load and outside weather conditions. Outdoor activities, especially in Southern climates, are often times performed during under hot weather conditions. The body tries to maintain its resting temperature of 98.6° F., by moving extra heat to the skin via the blood. Through evaporation of sweat, the heat dissipates into the air. At the same time, blood must also carry oxygen and nutrients to the muscles and remove wastes products from muscle metabolism. The higher the body's core temperature, the more blood is used for cooling and less is available for supplying muscles with oxygen and nutrients. Therefore, the cooler the body stays during exercise, the better muscles will function.

[0008] Many environmental and biophysical conditions cause elevated body temperatures. Clothing and environmental conditions are the factors that play the primary role in the body's ability to maintain a comfortable temperature during exercise.

[0009] U.S. Pat. No. 5,484,448 to Steele et al. discloses a cooling garment with opposing outside front and back panels. The garment substantially covers the user's torso and comprises rectangular elongated pockets affixed to the outside panels for retaining a plurality of cooling packs. The '448 patent teaches that the plurality of the elongated pockets cover a majority of the portion of the cooling garment covering the torso of the user. The Steele patent discloses a zipper that zips vertically in the center of the garment, not providing any direct means for cooling the central chest region.

[0010] U.S. Pat. No. 5,692,238 to Watson, Jr. describes a garment having outside pockets or other enclosures capable of mounting cooling packs such as gel packs therein. The '238 patent discloses thermally sensitive indicators, such as sensitive color guage strips to display the current effective temperatures of the gel packs. The Watson, Jr. patent teaches that many different types of garment may utilize the principles behind this invention including headbands, wristbands and body vests.

[0011] Neither of the above-referenced patents discuss or resolve the problem of cooling the meridian of the heart so that the temperature of the blood entering the lungs and aorta is lowered thereby increasing circulation and avoiding overheating and heat exhaustion.

[0012] Definitions

[0013] Heart Meridian: Traditional Chinese medicine practitioners believe these meridians conduct energy, or qi, between the surface of the body and internal organs. The term “heart meridian” as used throughout this application refers to the heart and the portion of major blood vessels entering and exiting the heart immediately surrounding the heart. This area, illustrated in Appendix A, generally includes the right ventricle of the heart, the aorta, the superior and inferior vena cava.

[0014] Cryotherapy: The local or general use of low temperatures in medical therapy. Also called crymotherapy.

SUMMARY

[0015] This invention relates to an innovative cooling apparatus for use in cryotherapy to reduce the physiological effects of overheating during strenuous physical activity. Placing one or more cooling pouches over the central chest region lowers the temperature of that region. Lowering the temperature of the heart meridian in turn lowers the blood temperature of blood flowing through the heart to allow the heart to pump more oxygen-rich blood throughout the body. The cooling apparatus utilizes sportswear and a multi-walled insulation pouch attached to the sportswear. The pouch can be filled with a freezable fluid such as water or a cooling gel. In one preferred embodiment of the cooling apparatus, the pouch is positioned within the sportswear so that the cooling pouch lies adjacent the heart meridian of a human body. By positioning near the heart meridian, the blood in the right ventricle, the arteries leading to the lungs and veins entering the heart are cooled thereby resulting in lowering the body's temperature.

Preferably, the pouch has at least one sealable end. An attachment means is located on the pouch, the attachment means is adapted to attach the pouch to the interior of sportswear so that the pouch lies adjacent to the heart meridian of a human body.

[0017] In an alternative embodiment of this invention the cooling apparatus comprises sportswear adapted to be worn on the upper part of the human torso. The sportswear can be a shirt, t-shirt, bra, a vest or a band that straps around the chest area. Preferably, the sportswear has an interior and an exterior and an attachment means. The attachment means is adapted to be positioned within the sportswear on the interior of the sportswear adjacent the heart meridian of a human body. In this embodiment, the multi-walled insulation pouch comprises a pouch attachment means located on the pouch for attaching the pouch to the attachment means located on the interior of the sportswear so that the cooling pouch is adapted to lie adjacent to the heart meridian when attached to the sportswear.

[0018] Preferably the multi-layered pouch comprises at least two layers of insulation material folded to form a pouch, one layer of insulation comprising cotton and another layer of insulation comprising nylon. Preferably, the cotton layer is the outer layer of the pouch and lies against the skin of the wearer. The pouch comprises at least one sealable end so that the pouch can easily be filled with the freezable fluid. The cooling pouch defines a cavity for receiving a freezable fluid, water or cooling gels. Advantageously, the cavity can be lined with a water proof material. In another aspect of this invention, the attachment means for attaching the pouch to the sportswear can comprise hook and loop material. Alternatively, the pouch can be sewn into the sportswear or attached by adhesive. Any known means of attachment can be used as long as the cooling pouch is within the sportswear and positioned adjacent the heart meridian.
